+- Fix: ``irr-as-set`` command, omit AS-SETs having a source different from the target registry.
+
+  The list of members used to build the IRR object no longer includes client's AS-SETs if their origin does not match the registry for which the object is being created.
+
+  See also `GitHub issue 126 <https://github.com/pierky/arouteserver/issues/126>`__.
+
+- Improvement: ``irr-as-set`` command, ``--include-members`` and ``--exclude-members`` options.
+
+  Add options to the command that allow the operator to include/exclude AS-SETs from the members list of the object being generated.
